MOP-HEAD AND IIVIPLEIVIENT CLAMP.

Specification of Letters Patent.

Patented May 8, 1906.

Application filed October 4, 1904. Serial No. 227,093.

T0 at whom it may concern-.-

Be it known that I, SIMEoN C. LAWLOR, a citizen of the United States,residing at Duluth, in the county of St. Louis and State of Minnesota,have invented certain new and useful Improvements in Mop-Head andImplement Clamps; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention relates to mop-head and implement clamps, and has for itsobject the provision of a clamp adapted to hold a mop or brush orscraper.

With this and other objects in view it con sists of the constructions,combinations, and arrangements of parts hereinafter described andclaimed.

In the drawings, Figure 1 is a plan View of said clamp. Fig. 2 is aperspective view of said clamp opened to receive a suitable brush. Fig.3 is a side elevation of said clamp, and Fig. 4 is a front sectionalelevation of the upper jaw of said clamp in open position.

In the drawings, 1 is a handle portion forked at one end, as at 2, andprovided at the ends of the tines of the forked portion withradially-corrugated or ribbed cheeks 3. Each of said checks is centrallyapertured for the passage of a bolt 4:. Secured to said forked portionis a j aw 5, provided with rearwardly extending radially corrugated orribbed ears 5 adapted to overlap said cheeks and in operation engagetherewith. Said ears are centrally apertured for the passage of saidbolt. The outer face of said jaw preferably has strengthening ribs 5formed thereon and is apertured for the passage of a locking-bolt 6,which bolt is curved to correspond approximately to the arc in which theapertured portion of the jaw willtravel when said jaw is opened from aclosed position. One end of said bolt 6 is fastened in any suitablemanner and at a suitable point to a second jaw 7, provided withrearwardly-extending ears 7 adapted to overlap said ears 5. Said ears 7a are centrally apertured for the passage of a thimble or sleeve8,surrounding the shank of said bolt 4 for a portion of its length. Theouter face of said jaw 7 preferably has strengthening-ribs 7 formedthereon. Formed upon the inner face of said jaw 7, a short distance backfrom the forward edge thereof, are a suitable number of spurs 9, adaptedto form back-stops for certain implements which may be insertedin saidclamp and to operate as teeth to grip larger implements which may beinserted in said clamp. The opposite said jaws preferably haverelatively opposite bends formed therein, as at 5 and 7 respectively,and other but shorter such bends 5 and 7 respectively, nearer theirforward edges, whereby said clamp is better adapted to grasp theimplements inserted therein. Upon one end of said bolt 4 is mounted awing-nut 4*, whereby said bolt may be set to draw said cheeks and ears 5into facial engagement with each other to maintain the jaw 5 at apredetermined angle with respect to said ferrule. A winged nut 6 ismounted on the free end of said bolt 6, whereby said jaws may be closedandlocked upon such mop or implement as it may be desired to clamptherein. Mounted upon said thimble or sleeve 8 is a coiled spring 10,one end of which bears against the inner face of one of said jaws andthe other end of which bears against the inner face of the other of saidjaws, whereby said jaws are forced open when said nut 6 is unscrewed orloosened.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is

1. In a mop-head and implement clamp, the combination of a forked handleportion, two jaws pivotally secured to the tines of said forked portion,locking means adapted to secure one of said jaws at a predeterminedangle to said handle portion, a bolt secured to one of said jaws andextending through an aperture formed in the other of said jaws, at anangle to the pivotal axis thereof, and adjustable retaining meansengaging said bolt and adapted to retain said jaws thereon and tolengthen or contract the space on said bolt available for the occupancyof said jaws, sub stantially as described.

2. In a mop-head and implement clamp, the combination of a forked handleportion,

two jaws piv'otally Connected therewith, and to secure said jaws in aclosed position,
